Answer:
99%, because as the level of confidence increases, Zc increases.
Step-by-step explanation:
45 goes into 240 5.33 times
The answer is 30. 5/10 is equal to 15/30
The given sequence is:

a(2)=1
a(3)=3
a(4)=9
We are to find the average rate of change between n=3 and n=4 for the given function.
Average rate of change =

So the average rate of change for the given function from n = 3 to n = 4 is 6
The answer is -2y•(2y^4 - 3y^2 - 4y + 1)
